LIN ER FOR VlSE-JAWS.

SPECIFICATION forming part of Letters Patent No. 758,838, dated May 3,1904.

Application filed June 4,1903. Serial ITO-159,997. (No model.)

To all 1071mm it III/(Ly concern.-

Be it known that I, ISAAC A. HERMANN, a citi- Zen of the United States,residing at Cleveland, in the county of (luyahoga and State of Ohio,have invented a new and useful Improvement in Liners for Vise-Jaws, ofwhich the following is a specification.

This invention relates to liners for vise-jaws, and has for its objectsthe production of a device of that character that lines both the innerface and the ends of the vise-jaw and one that is reversible, so thatwhen one end of the device is practically worn out it may be turnedaround and used as a new liner. These objects I attain in the structureshown in the accompanying drawings, in which- Figure 1 is a plan View ofthe blank from which my improved liner is made. Fig. 2 is a perspectiveview of a portion of a vise-jaw, showing aliner applied thereto and alsoshowing in dotted lines the position of the blank before it is bent downabout the jaw. Fig. 3 is a front face view of the jaw and liner shown inFig. 2, and Fig. 4: is an end elevation of the same.

Liners for vise-jaws are intended to prevent the marring of work thatmay be clamped in the vise. In order to protect the work effectuallyduring all kinds of operations to which such work is usually subjectedin a vise, it is necessary to have a lining for the end of the jaws. Byproviding my liner with projecting wings that are bent over said ends Iam able to clamp the work in any position and deliver the blows from thehammer in any direction without injury from the vise-jaws. Furthermore,by forming both ends of the blank alike I am able to reverse the blankwhen one end is worn, and thus make a practically new liner.

Referring now to the drawings, in which similar reference charactersdesignate corresponding parts throughout the several views, 1 representsthe vise jaw, and 2 the liner therefor.

\Vhile the drawings show but one jaw and one liner, it will beunderstood that each vise is provided with a pair of jaws, and that theliners of the pair being alike in construction they can be applied toeither jaw.

The blank from which the liner is constructed is shown in Fig. l, andconsists of a rectangularly-shaped body from the ends of which extend apair of projections a and b. That portion 0 of the blank between theprojections (4 forms the lining for the front face of the vise-jaw whenthe liner is first applied, and the projections a are bent at an anglethereto, so as to impinge against the ends of the jaws. Preferably theseprojections are bent so far as to cause them to grip against the jaw, asthey then assist in holding the liner in position. The main function ofthese projections is, however, to cover the ends of the jaws, so thatthe work cannot be damaged by being jammed thereagainst while in thevise.

\Vhile vises are of the same general shape and dimensions and linerscould be made of certain forms and sizes, and thus sold to the trade,itis preferable to bend the blank so as to fit the jaws accurately,which can best be done after the liner is clamped in the vise. In thiscase the liner would take the general position shown in dotted lines inFig. 2, from which position it is bent down to conform to the curvatureof the jaw. The projections 7) then extend outwardly, as shown in Fig.8, although they may be bent down against the jaw, if preferred.

WVhen the liner is practically worn out at the part 0, it is taken offthe jaw and straightened where it was previously bent, and that portion(Z is clamped in the vise. The projections 6 are then bent into grip theends of the jaw and the blank bent down to it the upper surface of thesame, when a practically new blank is formed out of the old one.

The liner may be made out of any suitable material and be of anyrequired thickness, and it may be made plain, corrugated, or of anyother desired finish. Preferably I make the liners of aluminium,as theyare then neat in appearance, light in weight, and are not easily damagedor quickly worn out.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A liner for a vise-jaw comprising a central section, and portions Oand l) on opposite sides of said section, said portions adapted to beused successively to cover the face of the aw.

2. A liner for a vise-jaw comprising a central section, portions C and Don opposite sides of said section, said portions adapted to be usedsuccessively to cover the face of the jaw, and means for engaging thejaw to hold the liner in position.

3. In a liner for vise-jaws, a portion at each end that is adapted tocover the face of the vise, and projections at each end of saidportions, said projections being adapted to overlap the ends of the jawsand form a lining therefor, the liner being constructed so that it maybe reversed when one of said portions is Worn.

4:. In a liner for vise-jaws, a portion 0 for lining the front of thejaw, a pair of projeccis worn the liner may be reversed so that theportion dwill line the face of the jaw and the projections b will lineand clamp the ends of the same.

In testimony whereof I affix my signature in the presence of twowitnesses.

ISAAC A. HERMANN.
